摘要： Provided is an electric motor capable of cooling a stator without being increased in size with a small number of components and even with simple work. The electric motor includes ring-shaped sealing members (34) having flexibility and being arranged on an inner diameter side of a stator coil (22) so as to surround inner diameter portions of coil ends. Cooling oil flowing from an upper part of a housing into the housing flows downward through coil end oil paths (37, 38) formed by the sealing members (34), coil end covers (32, 33), and the coil ends.

摘要： A mist is generated by scooping up cooling oil using a lower end portion of a non-load side end plate. Air containing this mist is circulated by a centrifugal fan provided to a load side end plate to form a recirculating air current flowing through first through-holes in a rotor core and through a ventilation passage on the outside of a rotor in opposite directions. According to a cooling mechanism as above, a mist generated in at least one point in the housing can be supplied with the recirculating air current to every point across a whole area within the machine. Hence, both of the rotor and a stator can be cooled efficiently with a small amount of mist.
摘要翻译：通过使用无负载侧端板的下端部舀取冷却油产生雾。含有该雾的空气通过设置在负载侧端板上的离心式风扇循环，形成流过转子铁芯中的第一贯通孔的循环气流，并通过转子外侧的通气通路。根据如上所述的冷却机构，可以在壳体中的至少一个点处产生的雾流通过机器内的整个区域的每一点供应循环气流。因此，能够以少量的雾来有效地冷却转子和定子。
